Question

Give geographical reasons: Vegetation is scarce in the high altitudes of Himalayas.

Hint:

When answering geographical reasons, always focus on cause and effect. Explain the natural factors (such as climate, location, or landforms) that lead to the observed geographical phenomenon. Be clear, concise, and support your answer with relevant examples.

Answer 1

Geographical Reason: The Himalayan region experiences extreme climatic conditions, which significantly affect vegetation growth. The key factors responsible for sparse vegetation at high altitudes include:

Low Temperature: As altitude increases, temperature decreases, making it difficult for plants to survive in the harsh cold conditions.
Heavy Snowfall: The Himalayas receive substantial snowfall, covering the land for most of the year and preventing the growth of vegetation.
Thin Atmospheric Pressure: Reduced oxygen levels and atmospheric pressure at high elevations make plant survival challenging.
Rocky and Barren Terrain: High-altitude regions mostly consist of rocky and steep slopes, which do not support fertile soil required for plant growth.
Short Growing Season: Due to long winters and extreme weather, the growing season for plants is very short, restricting dense vegetation.
Conclusion:
The combination of extreme cold, high altitude, and challenging terrain limits vegetation in the Himalayan highlands, with only hardy plant species like alpine shrubs and mosses surviving in some areas.
